Keywords: Quantitative Imaging, Quantitative Imaging, T1 mappingAn innovative cylindrical phantom is used to mimic a dynamic acquisition with temperature-induced changes in T1. Single reference (SR) variable flip angle (VFA) T1 maps are acquired at several rotational positions of this phantom, and are compared to corresponding T1 values acquired with the dual-angle variable flip angle and inversion recovery T1 mapping methods. The SR-VFA method of T1 mapping is shown to produce T1 accuracy within 4-10% of both inversion recovery and dual-angle VFA T1 measurements.
